From: Dave Hansen <dave.hansen@linux.intel.com>
The 'xfeature_bit's are at best xfeature bit _numbers_. Calling them bits is at best inconsistent with ending the enum list with 'XFEATURES_NR_MAX'.
This patch renames the enum to be 'xfeature_nr'. These also happen to be what the Intel documentation calls a "state component".
